Care & troubleshooting— extension-sourced, with citations
When to feed, prune & water
Attract beneficial insects and protect pollinators
Protection- Routine carePlant insectary flowers and tolerate light pestsstrong evidence — extension confidence
Grow a diversity of flowering plants (including small-flowered umbels and asters) to feed predators and parasitoids, and tolerate low pest numbers so natural enemies have prey to stick around.
- Routine careNever spray open bloomsstrong evidence — extension confidence
Avoid insecticides on flowering plants and apply any needed sprays in the evening when pollinators aren't active, and favor selective products over broad-spectrum ones to spare bees and beneficials.
Support monarchs on milkweed
Care- Routine careTolerate aphids; never spraymoderate evidence — extension confidence
Milkweed feeds monarch caterpillars and pollinators, so skip insecticides entirely. Oleander aphids look alarming but rarely harm the plant — knock them off with a water jet or wipe them off by hand and leave the rest for the butterflies.
